Tatcha's Luminous mask fit my face nicely, it didn't slip or slide while wearing. The packaging left serum to use afterwards, I'm not going to waste 1 drop! I used it on my neck and hands. While wearing I noticed a slight cooling feeling and in the hot, summer weather it was welcomed. After my time was up I simply peeled off the mask and put on a light moisturizer. Honestly, I think I could have skipped this step as my skin felt supple and looked refreshed. The mask hydrated my skin, gave it a cooling feeling, and left skin looking very dewy.
